snares LAMPJIX'IURE.

To all whom 5150 m Be it known that'I, OL'Ir'roN' Philadelphia, Pennsylvania, have invented certain'Improvements in Series Lamp-Ibrtures, of which the following 1s aspecrfica tion.

My invention relatesito series lamp fix tures employing sockets of the character shown in vPatent No. 960,807 and the ob ect .of my present invent-ioh is to ,provide a roper carIyh-ig structure or mount there or, such structure being supported in any suitable manner and preferably having means-for carrying a shade of the usual type employed. These. and other features of my invention are. more: fully described hereinafter, reference being had to the accompanying drawings, in which:

Figure 1, is a-plan 'view of my improved construction;-Fig. 2, is a sectional view on the line a a,F ig. 1; Fig. 3, is a sectional view on substantially the same plane as Fig,

2, illustrating a' slightly modified' construction, and Fig, 4, is'a sectional View on-the' line b-b, Fig. 3. l

{Series lam sockets are so well known at the present tune, aud myimproved form of socket bcingrclearly described in the patent before l stened to, there is no necessity of discussing their purpose.

The-present fixture structure comprises in general four elements;.that is to say, an upper invertedcup-likeshell or canopy l attachable to, a bracket or other support; aninsulating element 2; a depending shade.

holder 3, and a socket element 4, which latteris threaded into the element 2, in the well known manner.

The socket member or lamp receptacle 4:-

has within the same a threaded shell 5 of the well known Edison type. The base member 2 is provided with an internally threaded -shell 6, into which a similarly threaded metal shell 7 carried on the exterior of said socket member 4, may be screwed. Uponone side of the base 2 is a terminal 8, with which a contact strip 9 is connected; such strip extending across the center of thecent-ral recess 10 of the base specification of Letters ratent.

socket member 4. is screwed into position, a contact. p ece 13 mounted upon vthe same, preferably resilient and constituting a coning electrical connection between the terminal-8 of the base and the central terminal 1-3 of the socket' member, and also raising said contact strip 9 out of engagement with the contact strip 11, as shown.- i

As may be noted upon reference to the drawings, the threaded shell 5 is electrically connected withthe exteriorly threaded shell 7 of .the socket member, while the threaded shell/6 of the base member is electrically connected with the terminal 12. 'It will be ducting member, engages a metallic projec-" tion .14 on the contact strip 9, thereby fornrreadily understood, there-fore, thatjafter a lamp has'becn screwed into the shell 5, the

socket member 4 'may be entered into the base member andelectrically placed in cir-' cuit by -raising ftlr, springstrip 9 without occasioning the slightest jar to the lamp.

In the present construction, the insulating base member 2 has an upwardly extending" annular fiangeor wall 20 formim a central well or space, which provides su icient room for the placingof the necessary wires forming connections with a suitable source of current for the structure.- The outer surface of this annularwall is recessed at 21 for the reception of nuts 22, held in place .by.

pins 23 adapted to'pass through holes in said flange above lt-he nuts in the manner indicated, and the sustaining element or canopy lniay be'attached to said base member by means of screws 24 which enter said nuts. .This sustaining .or supporting memher or canopy 1 may rest up'onor engage an outwardly extending annular 'flange 25, which projects beyond thelowerportion of the base member 2 and performs the function of a rain shield or guard. Said base U clamps 01 connectors 30. .These'clamps are provided withindepcndent apertures or recesses for the receptlon of current conductmg wires which may enter from the side,

in the form of the structure shown in Figs.

' 1 and 2, or from the top through the supporting element or, canopy l, in the form of the structure shown in Figs. 3 and 4:. This lower wall of the base member is also recessed at 31 for the reception of nuts 32 into which screws 33 may be entered to support the shade holder 3, and this holder may be flared outwardly around the lamp reeep t-acle' so as, to provide an ample rain shield,

. and be flanged at 34:. The lamp shade may be secured to said flange in the usual manner, by screws 35, for instance.

. 'In the structure shown in Figs. land 2, the shade holder 3 has outwardly projecting arms 36 upon which insulators 37 may be mounted and to which the leading-in wires are connected; being held thereto in any suitable manner. This member 3 is also apertured at 38 for thereception of insulating thimbles or bushings 39 through which the leading-in wires are passed.

I claim: v

1. The combination of a base member having a bottom recess provided with an internallythreaded shell, a canopy support connected directly to said base member and disposed above the same, and a shade holder connected directly to said base member and disposed'below the same.

2. The combination of a base member provided with an internally threaded shell, a eauopy'support connected to said base member and disposed above and overlying the same, and a, shade holder connected to said base member and disposed below the same,
